I could be wrong too, Cobber, but thats my understanding of it all. AFAIK the boost pressure is controlled electro-pneumatically from the ECU sensing the pressure at the intercooler and porting the...

Some word terminoligy differences here . Actuator adjustment shaft is my description of it , but the grub screw would be the limit adjust . This is how I have understood and answered it , so my blew...

Uuummmmm... agree wit the majority but just to clarify a few points...

VNT grub screw adjustment - will control spool up not boost pressure but helps reduce pressure spikes by slowing the spool up...

Yes You take controll of boost as you have now bypassed Vacuum solenoid and ECU

Yes I never bothered tinkering with the grub screw as it is so difficult to get at . Mine peaks at 17 psi but normal driving hovers at 12-13 psi . before fitting dawes it used to peak at 22psi...

The grub screw is to limit max boost . When fitting dawes valve , most people plumb it bypassing the vacuum / ecu control solonoid . This makes it full manual control and take it from me , It is so...

Hey mate seen as you already have the boost and egt you are in good shape, definatley block that egr if not already done. The dawes valve and needle valve should be done without question it will...
